Abstract: A high voltage valve arrangement includes a high voltage valve unit; an external electric shield structure arranged at least partially around the high voltage modular valve unit and a grounding system. The grounding system includes a grounding system configured to be remotely extended from a retracted position to an extended position, whereby the extendable grounding device establishes electric connection with the external shield structure when it is extended from the retracted position.

Abstract: A semiconductor assembly includes a stack with a semiconductor module and a cooler, wherein the semiconductor module is provided in contact with the cooler. A clamping assembly is adapted to exert a force on the two sides of the stack. The stack is provided with a through hole between the two sides thereof and a part of the clamping assembly including an electrically conductive part which extends through the through hole of the stack. Thereby, a compact mechanical arrangement is provided while obtaining improved electrical properties, such as lower inductance and more even current distribution.
